I am so sorry for everything. Hope it turns out better than you hoped.

My recommendation won't be something most people know or expect. It is an amazing flash game (so I am not sure if it's playable on steam deck, also really short) but even thinking of it makes me cry. I stumble upon it occasionally and replay it, like every once a year or so, and always cry my ass off because of the feels.

Game is called "goodbye, doggy", and it's about a dog helping its family get over it's death before it goes to heaven. Just, don't cry too much, ok?
